Section 279.53. Effluent limitations guidelines representing the degree of effluent reduction attainable by the application of the best available technology economically achievable (BAT).

 

(1)  Except as provided in 40 CFR 125.30 - 125.32 , any existing point source subject to this subcategory shall achieve the following effluent limitations representing the degree of effluent reduction attainable by the application of the best available technology economically achievable (BAT): - See PDF for table

1 See footnote following table in s. NR 279.13 (4) .

(2)  The limits set forth in sub. (1) shall be multiplied by the following factors to calculate the maximum for any one day and maximum average of daily values for 30 consecutive days.

(a) Size factor. - See PDF for table

(b) Process factor. - See PDF for table

(3)  

(a ) In addition to the provisions contained above pertaining to COD, ammonia and sulfide any existing point source subject to this subcategory shall achieve the following effluent limitations representing the degree of effluent reduction attainable by the application of the best available technology economically achievable (BAT). For each of the regulated pollutant parameters listed below, the effluent limitation for a given refinery is the sum of the products of each effluent limitation factor times the applicable process feedstock rate, calculated as provided in 40 CFR 122.45 (b) .

(4)  The provisions of s. NR 279.13 (4) apply to discharges of process wastewater pollutants attributable to ballast water by a point source subject to the provisions of this subcategory.

(5)  The quantity and quality of pollutants or pollutant properties controlled by this subsection, attributable to once-through cooling water, are excluded from the discharge allowed by sub. (2) . Once-through cooling water may be discharged with a total organic carbon concentration not to exceed 5 mg/l.

(6)  The following effluent limitations constitute the quantity and quality of pollutants or pollutant properties controlled by this subsection and attributable to contaminated runoff, which may be discharged after the application of the best available technology economically achievable by a point source subject to this subcategory.

(a) If wastewater consists solely of contaminated runoff and is not commingled or treated with process wastewater, it may be discharged if it does not exceed 110 mg/l total organic carbon (TOC) based upon an analysis of any single grab or composite sample.

(b) If contaminated runoff is commingled or treated with process wastewater, or if wastewater consisting solely of contaminated runoff which exceeds 110 mg/l TOC is not commingled or treated with any other type of wastewater, the quantity of pollutants discharged may not exceed the quantity determined by multiplying the flow of contaminated runoff as determined by the department times the concentrations listed in the following table: - See PDF for table

Table III-7, pp. 49-54. Microsoft Windows NT 6.1.7601 Service Pack 1 40 CFR 122.45 (b) reads as follows: The calculation of any permit limitations, standards, or prohibitions which are based on production (or other measure of operation) shall be based not upon the designed production capacity but rather upon a reasonable measure of actual production of the facility, such as the production during the high month of the previous year, or the monthly average for the highest of the previous 5 years. For new sources or new dischargers, actual production shall be estimated using projected production. The time period of the measure of production shall correspond to the time period of the calculated permit limitations; for example, monthly production shall be used to calculate average monthly discharge limitations. - See PDF for table Microsoft Windows NT 6.1.7601 Service Pack 1 See the comprehensive example in s. NR 279.43 (3) (b) . Microsoft Windows NT 6.1.7601 Service Pack 1 1 In any case in which the applicant can demonstrate that the chloride ion concentration in the effluent exceeds 1000 mg/l (1000 ppm), the department may substitute TOC as a parameter in lieu of COD. A TOC effluent limitation shall be based on effluent data from the particular refinery which correlates TOC to BOD 5 . If in the judgment of the department, adequate correlation data are not available, the effluent limitations for TOC shall be established at a ratio of 2.2 to 1 to the applicable effluent limitations for BOD 5 .
